You wanna max your Q first it helps to use your Q when engaging into a fight.Your W is good during fights or after fight as a clean up or to confirm kills.

During early game you don't wanna be to aggressive. But it would help if u grab two kills early.
I usually have a tank with me to take the damage as I get the kills.The tanks I like to have with
me are either Vollibear or Leona.

The Boots of speed help early game with chasing down the enemy champs.It also helps when u get to engaged and need to run. Corki is a Attack Damage Carry you need to carry your team.
